Windows和Linux下Python输出彩色文字的方法教程

前言

最近在项目中需要输出彩色的文字来提醒用户,以前写过,但是只能在win上面运行。

今天搜了下看有没有在win和Linux上通用的输出彩色文字的模块,结果发现没有,,于是就自己弄了一个,分享下,以后用的时候翻翻博客,方便别人也方便自己。

win下输出彩色文字,网上有两种方法一种是用system执行命令来设置颜色,感觉还是不太好,用ctypes模块实现更好点。

linux下设置颜色,网上只找到了一种方法,下面不废话了,直接贴下代码:

示例代码


    import platform
    if 'Windows' in platform.system():
     import sys
     import ctypes
     __stdInputHandle = -10
     __stdOutputHandle = -11
     __stdErrorHandle = -12
     __foreGroundBLUE = 0x09
     __foreGroundGREEN = 0x0a
     __foreGroundRED = 0x0c
     __foreGroundYELLOW = 0x0e
     stdOutHandle=ctypes.windll.kernel32.GetStdHandle(__stdOutputHandle)
     def setCmdColor(color,handle=stdOutHandle):
     return ctypes.windll.kernel32.SetConsoleTextAttribute(handle, color)
     def resetCmdColor():
     setCmdColor(__foreGroundRED | __foreGroundGREEN | __foreGroundBLUE)
     def printBlue(msg):
     setCmdColor(__foreGroundBLUE)
     sys.stdout.write(msg + '\n')
     resetCmdColor()
     def printGreen(msg):
     setCmdColor(__foreGroundGREEN)
     sys.stdout.write(msg + '\n')
     resetCmdColor()
     def printRed(msg):
     setCmdColor(__foreGroundRED)
     sys.stdout.write(msg + '\n')
     resetCmdColor()
     def printYellow(msg):
     setCmdColor(__foreGroundYELLOW)
     sys.stdout.write(msg + '\n')
     resetCmdColor()
    else:
     STYLE = {
     'fore':{
     'red': 31,
     'green': 32,
     'yellow': 33,
     'blue': 34,
     }
     }
     def UseStyle(msg, mode = '', fore = '', back = '40'):
     fore = '%s' % STYLE['fore'][fore] if STYLE['fore'].has_key(fore) else ''
     style = ';'.join([s for s in [mode, fore, back] if s])
     style = '\033[%sm' % style if style else ''
     end = '\033[%sm' % 0 if style else ''
     return '%s%s%s' % (style, msg, end)
     def printRed(msg):
     print UseStyle(msg,fore='red')
     def printGreen(msg):
     print UseStyle(msg,fore='green')
     def printYellow(msg):
     print UseStyle(msg,fore='yellow')
     def printBlue(msg):
     print UseStyle(msg,fore='blue')

效果图:

Windows:


    C:\luan\lu4n.com-sqli>python
    Python 2.7 (r27:82525, Jul 4 2010, 09:01:59) [MSC v.1500 32 bit (Intel)] on win
    32
    Type "help", "copyright", "credits" or "license" for more information.
    >>> from color import *
    >>> printRed('Red')
    Red
    >>> printGreen('Green')
    Green
    >>> printYellow('Yellow')
    Yellow
    >>> printBlue('Blue')
    Blue
    >>> print 'http://lu4n.com/'
    http://lu4n.com/
    >>>

Linux:


    [root@Luan ~]# nano test_color.py
    [root@Luan ~]# python
    Python 2.7.5 (default, Jun 17 2014, 18:11:42) 
    [GCC 4.8.2 20140120 (Red Hat 4.8.2-16)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> from test_color import *
    >>> printRed('Red')
    Red
    >>> printGreen('Green')
    Green
    >>>

用起来很容易,直接from color import *就可以用了,有4种常用颜色可以使用,分别写了4个函数:

提示信息 printBlue

成功信息 printGreen

失败信息 printRed

警告信息 printYellow

和bootstrap的几种颜色差不多,应该够用了。
